Adenoid Cystic Carcinoma (ACC) of the Bartholin's gland misdiagnosed for three times: a case report

BACKGROUND

Adenoid cystic carcinoma (ACC) in Bartholin's gland is an uncommon malignant tumor. These tumors have a vague clinical feature, so they are diagnosed late and discovered at a high-level stage. Our case presented Three Recurrences and Three times Misdiagnosis of Adenoid Cystic Carcinoma (ACC).

CASE PRESENTATION

We report a case of adenoid cystic carcinoma arising in Bartholin's gland of a 64-year-old female patient that appeared after three previous vulvar tumors were excised. The patient underwent bilateral radiotherapy which was performed on the perineum.

CONCLUSION

ACC of the vulvar sweat glands is prone to misdiagnosis and delay in both diagnosis and treatment. As seen in our case, it was misdiagnosed three times as Chondroid Syringoma. Further studies need to be conducted to better understand the tumor prognosis, and its optimal treatment options.

Chondroblastoma of the patella with secondary aneurysmal bone cyst, an easily misdiagnosed bone tumor:a case report with literature review

Background

Chondroblastoma (CB) is a rare, primary, benign bone tumor that commonly affects men aged 15–20 years. It is usually detected in the epiphysis of the long bones, such as the proximal femur, humerus, and tibia. The patella is an infrequent site. CB with secondary aneurysmal bone cyst (ABC) is extremely rare in the patella, which can be easily confused with other common bone tumors of the patella. Thus, it is necessary to make the right diagnosis to get a good outcome.

Case presentation

We have presented here the case of a 30-year-old man who was suffering from anterior knee pain for the past 6 months that had aggravated 2 weeks before the presentation. Osteolytic bone destruction in the patella could be detected in both his X-ray and computed tomography (CT) examinations, while the magnetic resonance imaging (MRI) detected a fluid level. Accordingly, secondary ABC was presumed. We diagnosed the condition as giant cell tumor (GCT) with secondary ABC and, accordingly, performed curettage inside the focus region with autogenous bone grafting following the patient’s medical history, physical manifestations, results of physical and ancillary examinations, and the disease characteristics. However, the intraoperative and postoperative outcomes indicated that the patient’s histopathology was consistent with that of typical CB, suggesting a definitive error in diagnosis. Accordingly, the patient was finally diagnosed with patella CB along with secondary ABC.

Conclusions

Past studies have demonstrated that the 3 commonest bone tumors affecting the patella are GCT, CB, and ABC. CB with secondary ABC can be easily misdiagnosed as GCT with secondary ABC or ABC. Performing incision biopsy or excision biopsy and conducting histological examination may be the most effective method for suspected CB with secondary ABC.

Bladder perforation caused by long-term catheterization misdiagnosed as digestive tract perforation: A case report

BACKGROUND

Spontaneous bladder rupture is relatively rare, and common causes of spontaneous bladder rupture include bladder diverticulum, neurogenic bladder dysfunction, gonorrhea infection, pelvic radiotherapy, etc. Urinary bladder perforation caused by urinary catheterization mostly occurs during the intubation process.

CASE SUMMARY

Here, we describe an 83-year-old male who was admitted with 26 h of middle and upper abdominal pain and a history of long-term catheterization. Physical examination and computed tomography of the abdomen supported the diagnosis of diffuse peritonitis, most likely from a perforated digestive tract organ. Laparoscopic exploration revealed a possible digestive tract perforation. Finally, a perforation of approximately 5 mm in diameter was found in the bladder wall during laparotomy. After reviewing the patient’s previous medical records, we found that 1 year prior the patient underwent an ultrasound examination showing that the end of the catheter was embedded into the mucosal layer of the bladder. Therefore, the bladder perforation in this patient may have been caused by the chronic compression of the urinary catheter against the bladder wall.

CONCLUSION

For patients with long-term indwelling catheters, there is a possibility of bladder perforation, which needs to be dealt with quickly.

The Radiological Imaging Features of Easily Misdiagnosed Epithelioid Glioblastoma in Seven Patients

OBJECTIVE

We review the radiological imaging features and report histopathological findings of 7 adult patients with epithelioid glioblastoma (eGBM), which was a newly revised subtype of glioblastoma.

METHODS

Seven adult patients with a diagnosis of eGBM on a brain tissue specimen were retrospectively confirmed by pathology. The tumor magnetic resonance imaging characteristics such as location, number, edema, necrosis, hemorrhage, enhancement, diffusion-weighted image, apparent diffusion coefficient, magnetic resonance spectroscopy, dynamic susceptibility contrast-perfusion-weighted imaging, and histopathological findings were documented.

RESULTS

The tumors of these patients exhibited iso-hyperintensive signal on the T2-weighted image and iso-hypointensive signal on the T1-weighted image. All the lesions manifested iso-hypointensive signal on the diffusion-weighted image, and 2 cases showed significantly restricted hyperintensive signal (2/7). Peritumoral edema in all cases was mild. Five cases were located in the cortical lobe (5/7) and the other 2 were multifocal (2/7). Four cases showed white matter collapse sign (4/7). These tumors revealed apparent enhancement after contrast injection. In particular, 4 cases displayed capsuled sign (4/7), 2 cases showed dura mater tail sign (2/7), and 1 case showed hemorrhage (1/7). The mean value of apparent diffusion coefficient in 6 cases was 1.09 × 10^-3 mm²/s. The mean value of relative cerebral blood volume in 3 cases was 2.84 × 10^-3 mm²/s on dynamic susceptibility contrast-perfusion-weighted imaging. The average value of the choline/N-acetyl aspartate ratio in 4 cases was 6.47 × 10^-3 mm²/s on magnetic resonance spectroscopy. All cases expressed a BRAF V600E mutation according to molecular characteristics.

CONCLUSIONS

eGBMs that were predominantly located in cortex with mild peritumoral edema, white matter collapse, encapsular sign, and dura mater tail sign could be easily misdiagnosed as cortex-involved intracranial brain tumor such as meningioma, whereas multifocal tumors could be easily misdiagnosed as metastatic tumor and lymphoma. Multimodal images were helpful for the differential diagnosis.

A mixed method approach to understanding the factors surrounding delayed diagnosis of type one diabetes

AIMS

This study examined delayed type one diabetes (T1D) diagnosis, along with the associated severity markers, in the United States. Qualitative reflection was explored to add depth of understanding.

METHODS

975 parents of a minor child with T1D were recruited through snowball, social media requests to complete a 55-question online survey on the experience of diagnosis.

RESULTS

34% of children with T1D had a delayed diagnosis. When compared to those without a delayed diagnosis, these children were more likely to have an Emergency Room diagnosis (39.8% vs. 24.6%), be transported by ambulance or life flight (30.7% vs. 15.3%), be hospitalized (93.7% vs. 83.9%), spend time in an Intensive Care Unit (42.2% vs. 21.3%), and be in diabetic ketoacidosis (DKA) (42.2% vs. 21.3%). Younger children were at increased risk, with higher rates of DKA and fewer days of symptoms. Many parents experienced frustration receiving a prompt diagnosis for their child, including an inability to schedule a physician appointment, proper glucose testing, and concerns being dismissed by professionals.

CONCLUSION

More physician and parent education is needed. Doctors should conduct glucose screenings when diabetes symptoms are present. Parents need education to recognize excessive thirst and frequent urination as reasons to seek medical treatment.

Delayed presentation of uterine rupture in a didelphys uterus misdiagnosed as appendicitis: a case report and review of the literature

INTRODUCTION

Uterine rupture during pregnancy caused by uterine dysplasia, such as the double uterus, is very rare and easily overlooked by the surgeon.

CASE

A 25-year-old woman, at 17 weeks of gestation presented to our emergency center with acute right lower abdominal pain for more than 10 h. The initial diagnosis is acute appendicitis, but during the exploration, we found about 2500 mL of intraperitoneal hemorrhage, appendix was normal, pregnancy in one of the double uterine and ruptured at the right bottom. The pregnancy was removed and the uterine defect was repaired.

CONCLUSION

Uterine rupture caused by double uterus is very rare and easily Ignored by the surgeon. The survival of patients suffered from uterine rupture depends on the time interval between rupture and intervention.

Cholecystocolic fistula caused by gallbladder carcinoma: Preoperatively misdiagnosed as hepatic colon carcinoma

Cholecystocolic fistula secondary to gallbladder carcinoma is extremely rare and has been reported in very few studies. Most cholecystocolic fistulae are late complications of gallstone disease, but can also develop following carcinoma of the gallbladder when the necrotic tumor penetrates into the adjacent colon. Although no currently available imaging technique has shown great accuracy in recognizing cholecystocolic fistula, abdominopelvic computed tomography may show fistulous communication and anatomical details. Herein we report an unusual case of cholecystocolic fistula caused by gallbladder carcinoma, which was preoperatively misdiagnosed as hepatic flexure colon carcinoma.

AML M7 Misdiagnosed as ALL

Hematogones, which are normal precursors of B lymphocytes in the bone marrow, may be mistaken for blast cells on flow cytometry and histology when their numbers increase. We report such a case in a 16 months old male who was unsuccessfully treated for a pre-B cell ALL on the basis of flow cytometry of the bone marrow which showed a substantial population of CD19 and CD10 expressing 'blast' cells. A diagnosis of AML M7 was made on a subsequent bone marrow biopsy in which the blast cells expressed CD61 and Factor VIII, while they were negative for CD10 and CD20. Also present were a few CD10 and CD20 expressing small lymphoid cells, which were interpreted as hematogones. This report reiterates the problem of mistaking hematogones for 'blast' cells on flow cytometry, especially in the marrow of very young children where hematogones are often prominent.

Uterine leiomyoma associated non-puerperal uterine inversion misdiagnosed as advanced cervical cancer: A case report

INTRODUCTION

Uterine inversion is an un-common complication of parturition which often occurs in the immediate postpartum period. The chronic (non-puerperal) uterine inversion is rarer and most times tumour associated.

PRESENTATION OF CASE

A 51-year old grand multiparous lady presented with a month history of abnormal vaginal bleeding associated with offensive vaginal discharge, lower abdominal pain and dizziness. The initial evaluation suggested severe anaemia secondary to advanced cervical cancer. Examination under anaesthesia (EUA), staging and biopsy was attempted but this was however inconclusive due to profuse haemorrhage. A repeat EUA revealed chronic uterine inversion secondary to fundal submucous uterine leiomyoma. Myomectomy was done with tissue histology confirming benign uterine leiomyoma. Two weeks later, a modified Haultain's procedure was done followed by simple hysterectomy and posterior colpoperineorrhaphy. She had satisfactory recovery.

DISCUSSION

This is the first reported case of chronic non-puerperal uterine inversion in our hospital. When it occurs, it is usually tumour associated with the commonest tumour being prolapsed myoma and leiomyosarcoma. The diagnosis is based on high index of suspicion.

CONCLUSION

Chronic uterine inversion is a rare gynaecological condition and can be misdiagnosed as advanced cervical cancer or other causes of severe genital haemorrhage in women. A high index of suspicion is needed for its proper diagnosis. Sometimes, an EUA and biopsy was required to determine the cause here and conveniently it could be described as a “gynaecolological near miss”.
